You really should try to follow the basic rules of spelling, grammar and punctuation.
If the basis of the probation violation charge is that your boyfriend didn't take anger management classes, and his sentence and terms of probation do not include a requirement that he take anger management classes, then he and his lawyer should not have serious difficulty establishing that his failure to attend those classes is not a violation of his probation. If he was ordered to take anger management classes and failed to do so, he violated his probation. I'm not seeing how it would be an issue that the court didn't send him a written copy of the order if he was told of the requirement when he was sentenced in open court or by his probation officer. If he needed additional documentation for some reason, for example to take the classes in another state, he should have been proactive about obtaining it from the court.
Broadly speaking, the maximum period of incarceration you can receive for a probation violation is whatever remaining time you have to serve on the underlying charge.
